    Good Day All,

    I am trying to setup an ftp server at home so I can make some files
    available over the internet. I am using VSFTP with redhat 8.0 and it works
    fine as long I use the IP of my server at home provided by ISP. Here is the
    trick, instead of using
    ftp://192.168.1.1/docs I want to be able to use something like
    ftp://training.linuxathome.com.

    I don't have a lot of networking background, so please bare with me and
    hopefully by answering these I'll have better Idea where to start.

    1) Do I need to setup DNS ?
    2) If I do, that means I need to have domain name hosted by my ISP, correct?
    3) I heard that some companies offer free DNS hosting, if that is correct,
    who are these companies?
    4) what is the best way to approach this?

    Your help is greatly appreciated.
    Thank you

    You do not need to set up a DNS server, it's sufficient to
    have a suitable DNS record at a willing public server.

    Have a look at <http://www.dyndns.org/>.

    There are other similar services, Google for 'dynamic dns'.

    PS. I'm happily using Dyndns services - they work like the
    proverbial charm.

    Domain Name Howto

    These are the steps that you need to follow in order set up your
    domain name:
    *
    Purchase a domain name from a registrar.
    *
    Find a DNS name server to be authoritive for your domain.
    *
    Configure your name server's DNS records for your domain.
    *
    Let your registrar know who is the authorative name server for
    the domain.

    Getting A Domain Name

    Getting a domain name is relatively straight forward, you find a
    domain name registrar, chose a name that's not already registered, and
    pay the fee. All of this can be done via the registrar's website.
    Registration is for a fixed period of time, the minimum time being one
    year. A list of accredited registrars can be found at ICAAN. There are
    quite a few bargain registrars where the price is under US $10 per
    name per year, so shop around before you buy. Make sure that you chose
    a registrar that will allow you to configure your account online (more
    about that later).

    The .com, .net and .org domain names are freely available for
    registration by anyone. But virtually any name that's in the
    dictionary will have already been taken, either by someone who
    actually uses it, or by someone whose speculating that they can sell
    it to someone else at a profit. Names made from groups of words are
    more likely to be available. There's no way that you'll get hotel.com,
    but you could well find that you can get TheBrisbaneHotel.com. You
    have to be a bit creative. The registrar's web site will be able to
    tell you if the domain you want is available.

    The registrars for country specific domains (such as mydomain.com.au,
    au for Australia ) may be more restrictive. They may require that your
    domain name is the same as your company or organisation name, and the
    registrar may not allow these names to be sold to a third party. You
    are also less likely to find a bargain rate.
    Your Domain Needs An Authoritive Name Server

    Once you've got a domain name, you have to make it point to your host
    site. That is to say, you have to make the name resolve to the ip
    address of your host site. This is where the Domain Name System (DNS)
    comes in.

    Computers on the internet find each other using ip addresses, people
    find computers on the internet using their domain names. The Domain
    Name System maps domain names to ip addresses. DNS is based on a
    globally distributed network of name servers. A query to a DNS name
    server will yield the ip address of the submitted domain. The name
    server is said to resolve the name to an ip address. Your domain needs
    a DNS name server that's authoritive for it.

    When your web browser (or email client or whatever) tries to contact
    another computer on the internet, it asks the closest name server for
    the ip address for that computer's domain name. This name server will
    'ask around' other name servers and will find the name server that is
    authoritive for the domain. The authoritive name server will relay the
    ip address back to the requesting application.

    You have to designate a specific DNS name server to be the authoritive
    server for your domain name. You can use your ISP's name server, but
    you'll most likely have to pay for the service. Your domain name
    registrar may also provide this service, possibly for a fee. But there
    are free DNS name servers if you look around, Google 'free DNS'. You
    also have the option of hosting your own authoritive name server, but
    unless you're a large organisation with a fixed ip address and
    multiple servers, it won't be worth the trouble. A good, free DNS
    service can be found at www.zoneedit.com.


    DNS Records

    When you've found someone to provide a DNS service for you, create an
    online account with them and add your domain name to it. Now you have
    to configure your name server with information about your domain. This
    is done mainly with the 'A' record and 'MX' record.

    The 'A' record lists the ip addresses for your domain. Each ip address
    will have one or more names associated with it, either the domain name
    itself, and/or associated subdomain names.

    If you have a mail server its name must be in the 'A' record and thus
    have an ip address associated with it. This name will also have to be
    entered in the 'MX' record, designating it as the mail server.

    Your domain can have as many subdomains as you like. Each subdomain
    has it's own entry in the 'A' record, its own ip address. The ip
    addresses can be different, or the domain and subdomains can share the
    same address. Two common subdomains are 'www' and 'mail'. The 'www'
    subdomain often shares the same address as the domain, and you'll find
    that you can usually use either 'www.mydomain.com' or 'mydomain.com'
    in your web browser. The 'mail.mydomain.com' is often the entry found
    in the 'MX' record.


    Telling The World

    At this point you have a domain name and a DNS name server that will
    resolve that name to an ip address. But now you have to let the other
    name servers on the internet know where to find this authoritive name
    server for your domain. This is where you go back to your registrar
    and tell them where the name servers for your domain are. Notice that
    I've said name servers, plural. You need a second name server to act
    as a backup in case the first one goes down or is unreachable. But
    normally the DNS service that you use will provide you with both a
    primary and secondary name server. At the beginning of this howto I
    suggested that you use a registrar that allows you to configure your
    account online. This is where you configure your account so your
    domain name has an entry for both the primary and secondary name
    servers. Enter these in the appropriate place and that's it, except
    that now there's a bit of a delay. It will take somewhere between 24
    to 72 hours before this information propogates to other name servers
    on the internet. Don't expect name resolution for your domain to work
    reliably before this time.

  5. and your input answers the OP how?
    I think the OP didn't ask for a domain name howto, but rather on how to
    setup FTP at home and wether DNS was needed or not!

    This is what he said:
    That's all about domain names( resolving an ip address to
    training.linuxathome.com). That's exactly what the howto covers.
